SEO: Universal SEO Analysis Skill

Invocation: /seo $1 $2 where $1 is the command and $2 is the URL or argument.

Runtime: Run bundled Python tools through "${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run <script.py>. That is the single canonical form used by every skill and agent. Claude Code expands ${CLAUDE_PLUGIN_ROOT} to the installed plugin directory, so the launcher is found without any PATH entry; the repository ships no top-level bin/ directory because hosted marketplaces reject one. Repository users run ./scripts/claude-seo; manual installers rewrite the canonical form to "$HOME/.claude/skills/seo/scripts/claude-seo". Never invoke bundled scripts with a bare Python interpreter.

Comprehensive SEO analysis across all industries (SaaS, local services, e-commerce, publishers, agencies). Orchestrates 25 sub-skills (22 core + 1 framework integration + 2 extension mirrors) and 19 sub-agents. A separate optional Firecrawl extension is also installable (see "Optional Extensions" below).

Runtime Setup

Run setup only when the user explicitly invokes /seo setup or explicitly asks to repair dependencies. Execute "${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" setup, report core and Chromium status separately, and do not fall back to global or user package installation. For diagnosis, execute "${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" doctor --json; its output intentionally omits absolute paths and environment values. If any "${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run command reports that setup is required, suggest /seo setup and do not improvise a pip install.

Orchestration Logic

When the user invokes /seo audit, delegate to subagents in parallel:

1. Detect business type (SaaS, local, ecommerce, publisher, agency, other)
2. Spawn subagents: seo-technical, seo-content, seo-schema, seo-sitemap, seo-performance, seo-visual, seo-geo, seo-agentic
3. If Google API credentials detected ("${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run google_auth.py --check), also spawn seo-google agent
4. If Matomo credentials detected ("${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run matomo_auth.py --check), also spawn seo-matomo agent (alternative or complement to seo-google's GA4 reports)
5. If local business detected, also spawn seo-local agent
6. If local business detected AND DataForSEO MCP available, also spawn seo-maps agent
7. If backlink APIs detected ("${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run backlinks_auth.py --check), also spawn seo-backlinks agent
8. If Firecrawl MCP available, use firecrawl_map to discover all site URLs before analysis
9. If content strategy signals detected (blog, pillar pages, topic clusters), also spawn seo-cluster agent
10. If e-commerce detected, also spawn seo-ecommerce agent
11. If drift baseline exists for this URL ("${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run drift_history.py <url>), also spawn seo-drift agent
12. Always include seo-sxo in full audits (search experience applies to all sites)
13. Collect results and generate unified report with SEO Health Score (0-100)
14. Synthesize via the 10-principle framework (see "Synthesis Methodology" below), walk PERCEIVE → ANALYZE → VALIDATE → ACT before bucketing findings into Critical / High / Medium / Low
15. Create prioritized action plan with dependency sequencing + falsifiability per recommendation
16. Offer PDF report: "Generate a professional PDF report? Use /seo google report full"

For individual commands, load the relevant sub-skill directly. After any analysis command completes, offer to generate a PDF report via "${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run google_report.py.

Google update history questions (core, spam, policy, product changes; "is the spam update finished?"): answer from the bundled primary-source ledger, not from memory or other copies on disk. Run "${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run seo_updates.py --kind spam --json (or --since <yyyy-mm>; add --unverified for third-party claims that are not confirmed). If the output reports the ledger as stale, check status.search.google.com before stating that a rollout is complete.

Synthesis Methodology

Audits are not just findings, they are findings synthesized into a coherent strategy. claude-seo uses a 10-principle thinking framework grouped into four phases: PERCEIVE (observe-external · observe-internal · listen), ANALYZE (think · connect-lateral · connect-system), VALIDATE (feel · accept), ACT (create · grow).

Full audits (/seo audit, /seo page) walk every phase before emitting the action plan. Narrower commands (/seo schema, /seo images, etc.) pass at least THINK + ACCEPT before emitting (sound first principle, surfaced falsifiability). The Critical / High / Medium / Low priority buckets are the output of validation, not a substitute for it.

Full methodology + per-principle SEO mapping: references/thinking-framework.md (VALIDATE and ACT in references/thinking-framework-validate-act.md).

Each emitted recommendation should carry:

• The first-principle observation it rests on (THINK)
• The dependency on / unblock relationship to other recommendations (CONNECT-system)
• An explicit "how would we know this failed?" check (ACCEPT)
• A leading indicator the user can monitor without re-running the audit (GROW)

Industry Detection

Detect business type from homepage signals:

• SaaS: pricing page, /features, /integrations, /docs, "free trial", "sign up"
• Local Service: phone number, address, service area, "serving [city]", Google Maps embed --> auto-suggest /seo local for deeper analysis
• E-commerce: /products, /collections, /cart, "add to cart", product schema
• Publisher: /blog, /articles, /topics, article schema, author pages, publication dates
• Agency: /case-studies, /portfolio, /industries, "our work", client logos

Quality Gates

Read references/quality-gates.md for thin content thresholds per page type. Hard rules:

• WARNING at 30+ location pages (enforce 60%+ unique content)
• HARD STOP at 50+ location pages (require user justification)
• Never recommend HowTo schema (deprecated Sept 2023)
• FAQ schema: Google retired FAQ rich results for ALL sites on May 7, 2026 (no SERP feature anymore; supersedes the Aug 2023 gov/health restriction). Flag existing FAQPage at Info (not Critical); do not claim confirmed AI/LLM citation benefit; do not recommend removal; do not recommend new FAQPage for Google SERP benefit; use QAPage for genuine user Q&A
• All Core Web Vitals references use INP, never FID

Optional Extensions

The following ship in extensions/ rather than skills/ and require a separate installer to activate (see each extension's install.sh/install.ps1):

All optional extensions are reachable through /seo subcommands once installed: firecrawl, dataforseo, and image-gen, plus /seo ahrefs, /seo bing, /seo matomo, /seo profound, /seo seranking, and /seo unlighthouse. Each installs as its own sub-skill, so the model also auto-routes to their descriptions without the /seo prefix.

• seo-firecrawl -- Full-site crawling and site mapping via Firecrawl MCP. Install via extensions/firecrawl/install.sh (Unix) or extensions/firecrawl/install.ps1 (Windows). Once installed, invoke via /seo firecrawl <command>.
• seo-matomo -- Self-hosted or Matomo Cloud Reporting API as a GA4 alternative or complement. Install via extensions/matomo/install.sh (Unix) or extensions/matomo/install.ps1 (Windows). Once installed, invoke via /seo matomo <command> or rely on the audit orchestrator to spawn the seo-matomo agent automatically when credentials are present.

Subagents

For parallel analysis during audits:

• seo-technical -- Crawlability, indexability, security, CWV
• seo-content -- E-E-A-T, readability, thin content
• seo-schema -- Detection, validation, generation
• seo-sitemap -- Structure, coverage, quality gates
• seo-performance -- Core Web Vitals measurement
• seo-visual -- Screenshots, mobile testing, above-fold
• seo-geo -- AI crawler access, llms.txt, citability, brand mention signals

Error Handling

Scenario	Action
Unrecognized command	List available commands from the Quick Reference table. Suggest the closest matching command.
URL unreachable	Report the error and suggest the user verify the URL. Do not attempt to guess site content.
Sub-skill fails during audit	Report partial results from successful sub-skills. Clearly note which sub-skill failed and why. Suggest re-running the failed sub-skill individually.
Ambiguous business type detection	Present the top two detected types with supporting signals. Ask the user to confirm before proceeding with industry-specific recommendations.
